If you're restoring the system then you'll probably be booting using bootdisks or some such, so the running processes won't be from the binaries on the broken drive. Overwriting them shouldn't be a problem.
As far as configuration/data files and such for each specific application, you're probably going to have to look at documentation for each individual application. But as a guess, most configuration files or stored in either /etc or a .<app name> file/directory in your home directory.
To back up your named
configuration you'll have to archive /etc/named.conf and probably you're entire /var/named/pz directory.
